PROFILE
Berk Cem Goksel
Berk C. Goksel contributed to the torvalds/linux and google/syzkaller repositories by developing and refining USB audio and MIDI driver support, focusing on reliability and maintainability. Over two months, Berk enhanced fuzz testing coverage and improved device compatibility by expanding USB Audio Class connectivity and refining descriptor handling. Using C and Go, Berk addressed use-after-free vulnerabilities in ALSA USB audio drivers and implemented cross-architecture USB constant generation to support broader hardware. The work included code cleanup, regression fixes, and improvements to initialization logic, resulting in more robust USB subsystem behavior and increased stability for both development pipelines and production environments.
